Abstract

Vanadium trichloride forms 1:1 adducts with 6,6′-bis(hydrazino)-2,2′-bipyridines, in which the metal is in a six-coordinate environment, with the two axial sites occupied by chloride ligands. These complexes are paramagnetic and ESR active. Condensation of these complexes with 2,6-pyridinedialdehyde leads to either vanadium(III) macrocyclic complexes or free macrocyclic ligands, depending upon the conditions of pH.
